Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a private branch exchange system having a voice storing service function.

[0002]

2. Description of the Related Art In recent years, private branch exchange systems have various advanced functions and provide various high value-added services to users. One of these services is a voice storage service. This voice storage service processes the voice of a call made between an extension telephone terminal connected to a private branch exchange and an external line, by a voice storage processing attached to the private branch exchange. It is recorded on the device. This voice storage service is effectively used for the purpose of recording important call voice.

[0003]

By the way, in the case of recording a call voice by this voice storage service, it is necessary to notify the extension speaker of the fact that the voice will be recorded due to a problem such as privacy protection. Therefore, conventionally, for example, the extension speaker verbally notifies the speaker of the other party that the voice accumulation process is being performed. However, this is very annoying to the speaker, and the speaker sometimes neglects to notify, which is uncertain.

Further, in the past, the speaker could not judge whether or not the voice accumulation processing device was operating normally in order to record the voice of the call. Therefore, even though the speaker thinks that the voice of the call is being recorded, the voice is not actually recorded due to a breakdown of the voice accumulation processing,
The problem that important call voice is not recorded occurs.

A first object of the present invention is to provide a private branch exchange system which automatically notifies a caller that a voice storing process is being performed. A second object of the present invention is to provide a private branch exchange system by which a caller can judge whether or not the voice storage processing is normally performed.

[0006]

In order to achieve the above-mentioned first object, a first aspect of the present invention provides a plurality of telephone terminals to be connected.

[0008]

As a result, according to the first aspect of the present invention, for example, when one of the speakers makes a call voice storage request, the call voices of both speakers are stored and the call voices are stored. The message indicating that the private branch exchange will automatically notify the other party of the call. Therefore, for example, every time the speaker of the extension terminal makes a call, it is not necessary to verbally notify the other speaker that the call is being accumulated, thereby saving the speaker's trouble. In addition, the notification is not forgotten, so that it is possible to reliably prevent the occurrence of privacy-related troubles.

According to the second aspect of the present invention, for example, when one of the speakers makes a call voice storage request, the call voice is stored only when the means for storing the call voice operates normally. Further, when the call voice is further accumulated, the speaker is notified of a message as to whether or not the call voice is normally accumulated. Therefore, if the caller does not normally store the call voice due to a failure of the means for storing the call voice, etc., even if the caller requests the caller to store the call voice. It is possible to know that, and if the storage process is not performed, the speaker can record the content of the call by another means such as writing. Further, when the storage is normally performed, the speaker can confirm that the call voice is stored as requested.

n has an interface function between the office lines 51 to 5n and the private branch exchange A, respectively.

FIG. 2 is a block diagram showing the functional configuration of the central control unit 6. The central control unit 6 is a call control unit 6
1, a voice accumulation determination unit 62, a voice accumulation control unit 63, a transmission control unit 64, an LCD / LED control unit 65, a tone / talkie control unit 66, and the like.

The call controller 61 controls connection and disconnection of a communication path between the telephone terminals 31 to 3m and the office lines 51 to 5n. The voice accumulation determination unit 62 analyzes the call control signal and determines the voice accumulation request information.

The voice accumulation control unit 63 includes a voice accumulation determination unit 62.
Based on the result of the determination, the start-up, stop, connection and disconnection of the voice accumulation processing device 12 are controlled. In addition, the transmission control unit 64, based on the determination result of the voice accumulation determination unit 62,
Transmission control of message information indicating that voice information is to be stored or not to be stored to the telephone terminals 31 to 3m or the central lines 51 to 5n is performed.

The LCD / LED control unit 65 indicates that visual information stored in the ROM 9, that is, voice is stored.
Alternatively, control is performed to send a visible message indicating that the operation is not performed to the telephone terminals 31 to 3m or the office lines 51 to 5n. Further, the tone / talkie control unit 66 sends an audible information from the talkie device 10, that is, a voice message indicating that voice accumulation is performed or not, to the telephone terminal 3.
1 to 3 m or control for sending to the office lines 51 to 5 n.

Next, the operation of the private branch exchange system configured as described above will be described with reference to the flow chart shown in FIG. 3 and the sequence diagrams of FIGS. 4 and 5. In the present embodiment, the user of the telephone terminal 31 to 3m operates a predetermined function key of each telephone terminal 31 to 3m when making a call or during a call, or receiving a call from the public network N to the station line 51. The description will be made assuming that, in the case of occurrence, the accumulation of the call voice is automatically started. Further, the fact that the call voice is stored is notified to both the corresponding telephone terminals 31 to 3m and the public network N side, and the fact that it is not stored is notified to the relevant telephone terminals 31 to 3m by audible information, respectively, and the central control is performed beforehand. It is set in the section 6.

The central control unit 6 of the private branch exchange A first monitors the arrival of a ringing tone from the public network N in step 101. In this state, assume that a ringing tone is sent from the public network N as shown in FIG. Then, when the central control unit 6 detects the arrival of the ringing tone via the station line interface 41, the process proceeds from step 101 to step 102,
Here, it is determined whether or not the ringing tone comes through the station line 51, and when it arrives through the station line 51, it is recognized that there is a call voice accumulation request. In this case, the central control unit 6 supplies a sound recording start request from the sound storage control unit 63 to the sound storage processing device 12 in step 103 as shown in FIG. On the other hand, when the recording start-up completion is returned from the voice accumulation processing device 12, it is judged in step 104 that the voice accumulation processing device 12 has been activated successfully, and as shown in FIG. On the other hand, the ring tone is transmitted from the terminal interface 41.

Now, it is assumed that the speaker of the telephone terminal 31 answers the call off-hook. Then, the central control unit 6 of the private branch exchange A returns a response signal to the public network N, and then, in step 105, the transmission control unit 64 activates the tone / talkie control unit 66. Then, in step 106, the transmission of the recording start message is instructed.

Therefore, under the control of the tone / talkie control unit 66, a predetermined recording start message, for example, "Record the voice of the call" is generated from the talkie device 10, and this message is transmitted to the bus 7 and It is sent to the telephone terminal 31 via the terminal interface 21, and is also sent to the office line 51 via the bus 7 and the office line interface 41. After sending this recording start message, the central control unit 6 connects the voice storage processing device 12 to the speech path between the telephone terminal 31 and the public network N via the bus 7 and the communication path switch 1 in step 107. Let

Therefore, thereafter, the telephone terminal 31 side and the station line 5
The voice communication with the first side is stored in the voice storage processing device 12. Then, when the call ends and the speaker who originated the call ends the call, and the disconnection signal is sent from the public network N to the private branch exchange A via the central line 51, the central control unit 6 of the private branch exchange A 6 Executes the ending process. That is, the telephone terminal 3
When the user operates the key for designating the voice box number in No. 1, and the PB signal is sent by this, the P
The B signal is converted into a voice box number and transmitted to the voice storage processing device 12. The voice storage processing device 12 thereafter manages the stored call voice based on the designated box number.

On the other hand, it is assumed that a ringing tone from the public network N arrives at station lines 52 to 5n other than the station line 51. In this case, the central control unit 6 determines that there is no call voice storage request, and thereafter, the speaker of the telephone terminals 31 to 3m does not perform a predetermined function key operation for requesting call voice storage after the call is started. As far as possible, only the call processing is performed without performing the call voice accumulation processing.

Further, due to a failure of the voice accumulation processing device 12 or a lack of storage area, the voice accumulation processing device 1
When the recording start disabled is returned as shown in FIG. 2 to FIG. 5, the central control unit 6 performs steps 104 to 108.
Then, the sending control unit 64 activates the tone / talking control unit 66 to generate a predetermined recording-disabled message from the torch device 10, for example, "call voice cannot be recorded". It is transmitted to the telephone terminal 31 via the bus 7 and the terminal interface 21.
Therefore, the speaker of the telephone terminal 31 can know from this message that no recording will be performed.

As described above, in this embodiment, when an incoming call arrives from the public network N to the predetermined station line 51 as the designated station line for the recording request, the voice accumulation discriminating unit 62 makes a call voice accumulation request. If it is determined that the voice accumulation processing device 12 is activated via the voice accumulation control unit 63 and the activation is successful, the voice accumulation control unit 63 performs voice accumulation processing on the call voice from the telephone terminal 31 and the central line 51. In addition to being stored in the device 12, the transmission control unit 64 notifies the telephone terminal 31 and the speaker of the public network N that the call voice is stored in the telephone terminal 31 and the central line 51, respectively.

Therefore, according to this embodiment, the telephone terminal 3
1 and the speaker on the side of the central office line 51 can automatically receive a notification from the private branch exchange A that the call voice is to be stored, whereby the telephone terminal 31 and the caller on the public network N side store the call voice. It is possible to know for sure that processing is being performed. In addition, the user does not forget to notify that the call voice will be stored.

Further, when the voice accumulation processing device 12 is not activated, the transmission control unit 64 notifies the telephone terminal 31 that the conversation voice is not accumulated. It is possible to know that the storage processing has not been performed, so that the caller can judge that the content of the call is recorded by another means such as a secretary.

Further, since the transmission / control unit 64 activates the tone / talking control unit 66 to transmit the recording start message consisting of voice to the telephone terminal 31, the speaker of the telephone terminal 31 can store the conversation voice. Whether or not it is done can be known by a voice message in the telephone terminal 31. For this reason, whether or not the speaker is accumulating or not accumulating the call voice, for example, even if the speaker is blind and the speaker is not accustomed to handling the telephone terminal. You can know for sure.

The present invention is not limited to the above-mentioned embodiments, and can be carried out by appropriately modifying it within the scope of the invention.
For example, in the above-described embodiment, the operation of automatically starting the accumulation of the call voice when an incoming call is received from the public network N on the station line 51 is shown. However, when the user of the telephone terminals 31 to 3m makes a call. Alternatively, the call voice may be automatically started to be stored by the speaker performing a predetermined key operation in the telephone terminals 31 to 3 m to request the call voice to be stored.

Further, as described above, the notification that the call voice is to be stored or the call voice is not to be stored is sent to either the telephone terminal side or the network side, or both the telephone terminal side and the network side, depending on a predetermined setting. You can also do this. Further, in the above-described embodiment, the operation of storing the call voice or not storing the call voice is performed by the voice output. However, it may be notified by displaying a visible message on the LCD. .

[0032]

According to the first aspect of the present invention, for example, when one of the speakers makes a call voice storage request, the call voices of both speakers are stored and the call voices are stored. The private branch exchange will automatically notify the other speaker of the message that there is an error. Therefore, for example, every time the speaker of the extension terminal makes a call, it is not necessary to verbally notify the other speaker that the call is being accumulated.
The speaker's effort can be saved. In addition, the notification is not forgotten, so that it is possible to reliably prevent the occurrence of privacy-related troubles.

According to the second aspect of the present invention, for example, when one of the speakers makes a call voice storage request, the call voice is stored only when the means for storing the call voice operates normally. Further, according to the call voice accumulation request, the speaker is notified of a message as to whether or not the call voice is normally accumulated. Therefore, if the caller does not normally store the call voice due to a failure of the means for storing the call voice or the like even though the caller requests the caller to store the caller, It is possible to know that, and if the storage process is not performed, the speaker can record the content of the call by another means such as writing. Further, when the storage is normally performed, the speaker can confirm that the call voice is stored as requested.
